Oh, wow. The lighting in this is very clever and matches the message of the piece. The colors all reenforce the message. It's really quite warming, welcoming and comforting.
My only critique is that the perspective on some of your background elements (particularly the book shelf) are off. I'm really horrid with perspective, so unfortunately I can't give you tips other than using a ruler and a book on perspective the next time. :3
But, honestly? The first time I looked at this, I didn't notice the perspective issues at all, I simply admired the lighting and the "valentine's tree" you have there.
Wonderful work. :)
Very nice message and different Valentines Day twist. Typically i'm Anti-Valentines day, but I like this picture's focus and idea.
On an artistic note.. the lighting is very nice. I often have problems with that when I create my own pictures. For some reason the little cross is my favorite part of the picture though. I'm not quite sure why though..
Nice picture.
